TREE-PAINT AND METHOD or rnnranne SAME.

, To ([65 whom it may concern tecting the trunk of the t .Be it known that I, VVILIJIAM B. Q'rwnLL, acitizen of the'United States, resid ng at Carlinville, int-he county of Macoupin and State of Illinois, have inventedcertain new and useful Improvements in Tree-Paint and Methods of Preparing Same, of which the following is a specification. 1

M invention relates to a paint to be applied to fruit trees for the purpose of proee from animals p and insects.

It is theobject of my invention to providea paint for that purpose which maybe put up at the factory'in dry form and will keep,

after being put up until used without losing I any of its efiicacious properties. This dry timethe paint disintegrates upon the trunk of the tree and "will ultimately (in from four to six months time) be carried away to the roots of the treeswhere fertilizing constituents of the paint become available for plant-food.

Nicotin is well known to be an extremely effective insecticide. All tobacco contains nicotin, and tobacco dust maybe and is used quite generally for insecticide purposes. When, however, tobacco dust is mixed with a liquid for application in the form of a paint the nicotin crystals are immediately released from the substance of the tobacco dust and washed away with the first rains, so'that in the past tobacco dust has only been effective by means of repeated applications for immediate results.

I have discovered that air slaked lime in combination with Venetian red may be made into a paint with tobacco dust, and after the same has been applied and dried the lime and Venetian red will hold the nicotin in suspension in thebody ofthe paint and prevent the rains from washing the same awav except to the extent that the body of the paint itself is washed away. It also operates to free the nicotin from the tobacco dust and will in time combine therewith. 1 This freeing effect is gradual, however, and for that reason results satisfactorily when the paint gallon of the mixed paint.

is applied to the tree, but for thevsa-me reason the tobacco dust and lime cannot be mixed even in dry form until ready for application upon the tree. It is an, essential part of my invention that/my complete compound is prepared'dry in twoseparate parts which are mixed together with the necessary quantity of water just before the-same is applied to the tree. In practice, a sufficient amount of each of the sets of ingredients is prepared and packaged for mixing together with a given quantity of water to produce a certain determined quantity of paint.- The preferred proportions of ingredients for the mixture thereof containing tobacco dust is six parts by weight of powdered glue, six parts by weight Venetian red, one part by weight flour of sulfur, and one part by weight powdered tobacco dust. All of these ingredients must be powdered very fine and intimately mixed together. Fourteen ounces of'this mixture will be required to make one The other set of ingredients comprisesair slaked lime and Venetian red thoroughly pulverlzed and mixed together in the proportions of three parts of air slaked lime to one part of Venetian red. Five pounds two ounces of this mixture will be required for mixing a gallon of tree paint. In practice mixture number one, consisting of powdered glue, flour of sulfur, Venetian red and pow-- dered tobacco dust, in proportions= stated, will be out up in packages of fourteen ounces or multiples thereof, and mixture number two, consisting of air slaked lime and Venetian red, mixed in the proportions stated," Will be put up in packages of five pounds two ouncesor multiples thereof. These two packages of mixtures, numbers one and two, respectively, will be procured by the user and mixed with a gallon of water in the orchard andimmediately applied to the tree trunks. This paint should be applied early in the spring and may also be applied late in the fall. It will have entirely washed away by the end of summer, and that applied in the fall will practically all be off of the tree trunks by the following spring, so that application should be made both spring and fall. It is essential that the paint should wash ed as indicated because if it does not do so and were to remain permanently upon the bark of the tree it would both be injurious to the tree and fail to perform the insecticide functions for which it 1s primarily intended.

When used for winter I add to thepaint a mixture of coal tar and brown creosote in the vproportions of one part byweight of coal tar and two parts by weight of brown creosote, and of this mixture add six ounces to each gallon of winter tree paint. The mixture of tar and creosote will be shipped in sealed containers separate from the packages containing mixture number one and mixture number 2, and added to the paint in the orchard at the time of mixing.

I claim:

- 1. A tree paint consisting of glue, sulfur, tobacco dust, Venetian red, air slaked lime, water, coal tar and creosote intermingled and combined in the manner and approximately as specified.

2. The method of preparing a tree paint including tobacco dust as an insecticide, which comprises mixing together powdered glue, flour of sulfur, Venetian red and powdered tobacco dust, separately mixing air slaKed lime and Venetian red, separately packaging approximately fourteen ounces of mixture number one and approximately five pounds two ounces of mixture number two, and

mixing said setsof ingredients with water immediately before using in the proportion of one gallon of water for each fourteen ounces of mixture number one and fi've pounds'two ounces of mixture number two.

3. Themethod of preparing a tree paint including tobacco dust as an insecticide which consists in mixing together powdered glue, flour of sulfur, Venetian red and powdered tobacco dust, separately mixing air slaked lime and a Venetian red, separately mixing coaltar and creosote, separately Water for each fourteenounces of mixture number one, five pounds two ounces-0f mixture number two and six ounces of mixture number three.
